ISEssues authenticating SPA504G phone

pflatt — Tue, 06 Jun 2017 20:15:09 GMT

I am seeing soem weird issues with Dot1x and MAB when I connect a Cisco SPA504g phone. The initial Dot1x check starts and fails, and MAB then takes over. After it successfully authenticates and is authorized, I am seeing the device constantly re-authenticating.

I have copied some of the switch output below:

If anyone has any ideas on why this is occurring and how to stop it, I sure would appreciate some assistance.

Cheers

Timothy Abbott — Wed, 07 Jun 2017 13:19:13 GMT

Paul,

Are you wanting the phone to perform 802.1X authentication? The reason I ask is because it seems the phone has been configured to do so. Can you try re-configuring it so that it doesn't try 802.1X and see if that helps?

Regards,

-Tim

Hi Tim,

no I don't want to authenticate the phone using 802.1x, but I do want any device attached to it (PC/Laptop) to use 802.1x if it supports it.

My understanding is that these phones do not support 802.1x in a wired environment (from SPA500 Series IP Phone Administration Guide), so I am wondering if this is the cause of the issue.

I really don't want to have to remove 802.1x if I can help it.

Re: ISEssues authenticating SPA504G phone

Oliver Laue — Fri, 23 Jun 2017 03:23:43 GMT

Is the Phone Configured to use a Voice VLAN? If so it will notice it didn't get access to the Voice Domain and will permanently retry. Try to assign the Voice Domain Permission with your ISE and look if it's working.

Re: ISEssues authenticating SPA504G phone

pflatt — Fri, 23 Jun 2017 03:27:50 GMT

Hi Oliver,

The switch port has a voice VLAN and Data VLAN. Are you suggesting that I should change this and assign a VLAN using an ISE policy?

If so, what is your suggestion for best practice in this instance? I'm not familiar with doing it that way.

Thanks

create a authorization rule for the phones and use the default Cisco_IP_Phones Authorization Profile or create a new one with just the checkbox "Voice Domain Permission" marked.

Unfortunately that hasn't worked.

Looking at the ISE RADIUS Live Logs, I can see the device ping-ponging between Cisco_IP_Phone and Cisco_Device as it tries to reauthenticate or gets constantly profiled. The switch logs again show EVENT ATTACH followed by EVENT DETACH as per below

"speed auto 10 100" and "duplex full"?? It might be some Cat 6K. It might worth to try a different switch.

None of the outputs are telling why it DETACH within a second after authorized. I would suggest to engage Cisco TAC to troubleshoot.
